病毒描述：
该病毒是一个压缩文件，病毒运行后会打开一个图片，达到欺骗用户的目的，其中含有两个可执行的病毒文件和相关动态链接库。病毒运行后，会将自身相关文件复制到%system32%下，删除注册表项，终止相关服务，使杀毒软件失效，新建Internet服务，终止相关进程，并上网下载文件。
行为分析：
1、该病毒是一个文件，其中含有两个可执行的病毒文件：HLP.exe、SYN.exe。病毒运行后将自身文件复制到%system32%下：
%system32%mypic.jpg
%system32%packet.dll
%system32%wanpacket.dll
%system32%wpcap.dll
%system32%drivers
pf.sys
2、删除注册表项：

3、终止以下服务：
Windows Firewall/Internet Connection Sharing(ICS)
Background Intelligent Transfer Service
System Restore Service
SecurityCenter
Automatic Updates
4、新建注册表项：
HKEY_CURRENT_USERSoftwareMicrosoftWindows
ShellNoRoamMUICache
键值：字串：(原病毒所在路径)= "MyPic"
HKEY_CURRENT_USERSoftwareMicrosoftWindows
ShellNoRoamMUICache
键值：字串："C:WINDOWSHLP.exe"= "HLP"
HKEY_CURRENT_USERSoftwareMicrosoftWindows
ShellNoRoamMUICache
键值：字串："C:WINDOWSsystem32shimgvw.dll
"= "Windows 图片和传真查看器"
HKEY_CURRENT_USERSoftwareWinRAR SFX
键值：字串："C%WINDOWS%"="C:WINDOWS"
HKEY_LOCAL_MACHINESYSTEMControlSet001ServicesInternet
键值：字串："Description "="为 Internet 连接提供基础服务
，如果此服务被停止，多数 Internet 软件将无法正常运行。如果此服务被
禁用，任何依赖它的服务将无法启动。"
HKEY_LOCAL_MACHINESYSTEMControlSet001ServicesInternet
键值：字串："DisplayName"="Internet"
HKEY_LOCAL_MACHINESYSTEMControlSet001ServicesInternet
键值：字串："ImagePath "=""C:Program FilesWindows NT

HKEY_LOCAL_MACHINESYSTEMControlSet001ServicesInternet
键值：字串："ObjectName "="LocalSystem"
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesInternet
键值：字串："Description"="为 Internet 连接提供基础服务，如果此
服务被停止，多数 Internet 软件将无法正常运行。如果此服务被禁用，
任何依赖它的服务将无法启动。"
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesInternet
键值：字串："DisplayName"="Internet"
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesInternet
键值：字串："ImagePath "=""C:Program FilesWindows NT
lsass.exe" ServiceStart"
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesInternet
键值：字串："ObjectName"= "LocalSystem"
5、新建服务:
HKEY_LOCAL_MATHINSYSTEMCurrentControlSetServicesInternet。
(为 Internet 连接提供基础服务E，如果此服务被停止，多数 Internet 软件将无法正常运行。如果此服务被禁用，任何依赖它的服务将无法启动)
6、尝试关闭反病毒进程，如：
kav.exe
kavsvc.exe
Rav.exe
RavMon.exe
……
7、尝试下载：

http://notidgbwd*****rfreewebspace.com/
http://notidgbwdsg.5****.com/not_v1/not_ini_v1.jpg
……
注：% System%是一个可变路径。病毒通过查询操作系统来决定当前System文件夹的位置。Windows2000/NT中默认的安装路径是C:WinntSystem32，windows95/98/me中默认的安装路径是C:WindowsSystem，windowsXP中默认的安装路径是C:WindowsSystem32。

清除方案 ：
1、使用安天木马防线可彻底清除此病毒(推荐)。
2、手工清除请按照行为分析删除对应文件，恢复相关系统设置。
(1) 使用安天木马防线“进程管理”关闭病毒进程
(2) 删除病毒文件
%system32%mypic.jpg
packet.dll
wanpacket.dll
wpcap.dll
%system32%driversnpf.sys
(3) 恢复病毒修改的注册表项目，删除病毒添加的注册表项
